Hey Mark, can you elaborate on what you mean by the "arm cannot be tight"...? I must be missing something here.
Wait... You're talking about the nut which holds down the arm can't be overtightened. Never mind.
Yep, thats it. I have had mine fall out cause I keep it loose. I noticed on the newer MZE, there is a sleeve that comes out and keeps you from overtighening however. (I think)
